further, the inside of transfer passage 210 is provided with second baffle 216, and the top of second baffle 216 is connected with transfer passage 210 inner wall is articulated, the bottom and the transfer passage 210 inner wall of second baffle 216 laminate mutually, second baffle 216 seals the interface of transfer passage 210 and shell 110, make the dust in the shell 110 difficult outwards give off through transfer passage 210 and crushing storehouse 211, raw materials stone gets into transfer passage 210 and can overturn second baffle 216 left after being in, can not hinder the normal material loading work of the device.
The working principle is as follows: firstly, a user starts the first motor 114, the second motor 215 and the air pump 166, the second motor 215 drives the fourth rotating rod 212 to rotate through the output end of the second motor after being started, the fourth rotating rod 212 drives the fourth gear 214 to rotate when rotating, the second motor 215 drives the other group of fourth gear 214 to rotate simultaneously when rotating, and the other group of fourth gear 214 drives the other group of fourth rotating rod 212 to rotate, so that the two groups of crushing rollers 213 rotate, then the user pours the gangue raw material to be crushed into the crushing bin 211, and the rotating crushing rollers 213 crush the gangue raw material in the crushing bin 211, so that the larger gangue raw material is crushed into small pieces, the grinding roller 118 can crush the gangue raw material better, the crushing efficiency of the grinding roller 118 is improved, and the situation that the gangue raw material cannot be crushed smoothly due to overlarge stones is reduced;
then the raw material enters the conveying channel 210 and enters the shell 110 through the second baffle 216, the raw material stone falls down into the grinding sleeve 119, the first motor 114 is started to drive the main shaft 116 to rotate through the output end thereof, the main shaft 116 drives the grinding roller 118 and the sleeve column 140 to rotate, when the stone enters the gap between the grinding roller 118 and the grinding sleeve 119, the grinding roller 118 crushes the stone and crushes the stone into powder, some stone falls onto the sleeve ring 142 through the grinding roller 118, the rotating sleeve column 140 drives the sleeve ring 142 and the scraper knife 143 to rotate, when the sleeve ring 142 rotates, the stone and the powder on the sleeve ring 142 are thrown onto the scraper knife 143 along with inertia, the scraper knife 143 throws the stone and the powder again between the grinding roller 118 and the grinding sleeve 119 through inertia for grinding, in the process, the qualified fine powder material falls down onto the filter screen 138, the filter screen 138 screens the stone, the fine powder materials are discharged downwards to the inside of the material collecting bin 155 through the bottom end of the shell 110 to be collected by a user, the air flow is blown into the shell 110 after the air separator 167 is opened, large particle powder in the shell 110 is lifted, the large particle powder is continuously conveyed upwards through the separation of the air separator 167 and discharged, the large particle materials fall back to the inside of the shell 110 to be ground again, the discharging efficiency of the device is greatly improved, and the fine powder materials meeting the conditions can be rapidly discharged from the inside of the shell 110;
when the grinding roller 118 rotates, the grinding roller 118 drives the second moving rod 169 to rotate at the same time, the second moving rod 169 drives the pulley 170 to rotate, when the pulley 170 rotates to be in contact with the inner wall of the pressure groove 122, the pulley 170 applies pressure to the inner wall of the pressure groove 122, so that the moving plate 121 moves away from the grinding roller 118, the moving plate 121 drives the vertical plate 124 to move, so that the first spring 125 is subjected to pressure contraction deformation, the moving plate 121 drives the gear teeth 123 to move when moving, the moving plate 121 drives the first gear 127 to rotate through the gear teeth 123, the first gear 127 drives the second gear 129 to rotate, the second gear 129 drives the third gear 131 to rotate, the third gear 131 drives the transmission rod 132 to move when rotating, so that the angle of the transmission rod 132 changes, the transmission rod 132 drives the first moving rod 133 to move away from the grinding roller 118, and at this time, the sliding rod 136 slides inside the first sliding groove 137, the first movable rod 133 moves inside the limiting sleeve 134, the first movable rod 133 drives the connecting plate 135 to move away from the grinding roller 118, the second spring 139 and the third spring 145 are compressed and stretched to drive the filter screen 138 to move, when the pulley 170 moves to be no longer in contact with the pressure groove 122, the first spring 125 releases resilience to drive the movable plate 121 to reset, thereby driving the filter screen 138 to reset, the grinding roller 118 rotating at high speed enables the pulley 170 to be continuously in contact with and separated from the pressure groove 122, so that the filter screen 138 integrally generates a vibration effect, impact force generated when the grinding roller 118 rotates at high speed is weakened layer by layer through the first gear 127, the second gear 129 and the third rotating rod 130, so that the vibration amplitude of the filter screen 138 is reduced and is not easy to damage, the filter screen 138 in a vibration state can rapidly vibrate powder at the top end downwards, so that the filter screen 138 is not easy to block, and the screening efficiency of the filter screen 138, meanwhile, the first baffle 168 protects the pressure groove 122, so that damage to the pressure groove 122 caused by the fact that large-particle stone raw materials hit the pressure groove 122 when the pulley 170 is not in contact with the inner wall of the pressure groove 122 is avoided;
when the device is used for grinding, after the air pump 166 is started, air flow from bottom to top is generated, the air flow enables larger powder intercepted at the top end of the filter screen 138 to enter the powder inlet channel 151 and enter the second fixing rod 152 through the powder inlet channel 151, then the powder enters the powder outlet bin 148 through the conveying rod 147, finally the powder is discharged outwards through the powder outlet channel 149, the powder falls onto the sleeve ring 142 and enters the gap between the grinding roller 118 and the grinding sleeve 119 again for secondary grinding through the scraper knife 143, and therefore particles and powder at the top end of the filter screen 138 are conveyed and cleaned, and the probability of blockage of the filter screen 138 is reduced.
